一、前言
本教程重点在于supervisor的配置过程,celery的安装配置请参考其他教程
二、安装supervisor
1.安装命令pip install supervisor # supervisor目前只支持python2,但是作为容器来说,并不影响监控程序是python3的程序
2.执行 配置文件 生成命令
echo_supervisord_conf > /etc/supervisord.conf
3.创建配置文件需要的文件夹
mkdir /var/log/celery/
mkdir /var/log/celery/
mkdir /var/log/supervisor/
mkdir /var/run/supervisor/
4.更改权限
mkdir /var/log/celery/
mkdir /var/log/celery/
mkdir /var/log/supervisor/
mkdir /var/run/supervisor/
5.编辑配置文件 /etc/supervisord.conf 加入celery配置项(本配置中没使用beat)
; ==================================
; celery worker supervisor example
; ==================================
[program:celery]
; 如果使用的是虚拟环境(virtualenv等)要把celery命令路径写全
command=/home/hiveme/env/cznews/bin/celery worker -A cznews --loglevel=INFO
; Alternatively,
;command=celery --app=your_app.celery:app worker --loglevel=INFO -n worker.%%h
; Or run a script
;command=celery.sh
directory=/home/hiveme/cznews/ ;项目所在目录
user=nobody
numprocs=1
stdout_logfile=/var/log/celery/worker.log ;celery输出日志文件
stderr_logfile=/var/log/celery/workererr.log ;celery错误输出文件
autostart=true
autorestart=true
startsecs=10
; Need to wait for currently executing tasks to finish at shutdown.
; Increase this if you have very long running tasks.
stopwaitsecs = 600
; Causes supervisor to send the termination signal (SIGTERM) to the whole process group.
stopasgroup=true
; Set Celery priority higher than default (999)
; so, if rabbitmq is supervised, it will start first.
priority=1000
; ================================
; celery beat supervisor example
; ================================
;[program:celerybeat]
; Set full path to celery program if using virtualenv
;command=/home/hiveme/env/cznews/bin/celery beat --schedule /var/lib/celery/beat.db --loglevel=INFO
;command=celery beat -A myapp --schedule /var/lib/celery/beat.db --loglevel=INFO ;the ordinary
; remove the -A myapp argument if you aren't using an app instance
;directory=/home/hiveme/cznews/
;user=nobody
;numprocs=1
;stdout_logfile=/var/log/celery/beat.log
;stderr_logfile=/var/log/celery/beaterr.log
;autostart=true
;autorestart=true
;startsecs=10
; Causes supervisor to send the termination signal (SIGTERM) to the whole process group.
;stopasgroup=true
; if rabbitmq is supervised, set its priority higher
; so it starts first
;priority=999
三、启动supervisor(需要使用root权限)
supervisord -c /etc/supervisord.conf
四、启动过程中的问题(查看supervisord.log和celery的错误日志)
注意重启服务器1.INFO spawnerr: can't find command 'celery'(supervisord.log)
解决方案:
检查 celery是否安装在虚拟环境中,如果是在配置文件中 需要把所有celery的命令改成 完整的路径
2.INFO spawnerr: unknown error making dispatchers for 'celery': EACCES(supervisord.log)
主要是没有权限操作日志文件
解决方案:
chown youruser:youruser -R /var/log/supervisor/
chown youruser:youruser -R /var/run/supervisor/
chown youruser:youruser -R /var/log/celery/
chown youruser:youruser -R /var/log/celery/
3.exited: celery (exit status 127; not expected)(supervisord.log)
这日志报错,网上是说127是指命令不合法
但是当把命令单独拿到外面执行时也可以执行,进入celery日志查看后发现如下错误:
supervisor: couldn't setuid to 65534: Can't drop privilege as nonroot usersupervisor: child process was not spawned
还是说权限问题,
解决方案:
目前是通过root运行解决的,有更好办法的小伙伴可以和大家一起交流交流
4.supervisorctl: error: <class 'socket.error'>, [Errno 101] Network is unreachable: file: /data/openfalcon/open-falcon/python/lib/python2.7/socket.py line: 575
解决方案
运行supervisorctl时指定配置文件才可以正常运行supervisorctl,否则supervisorctl默认去/etc/supervisord.conf去读取配置,导致错误。
supervisorctl -c your/path/to/your/conf
